Sentence examples for convergent changes from inspiring English sources

This illustrates that convergence in complex phenotypes can arise via convergence in general genomic architecture, rather than convergent changes in specific genes.

Thus, the diverse lens crystallins were recruited by convergent changes in the regulation of unrelated genes.

The relatively few examples of such convergent changes are based largely on molecular and functional analysis of proteins with well-defined structures and functions; consequently, the inference of convergent adaptive polymorphism or divergence allows plausible arguments to be made regarding the phenotypic adaptive effects of particular mutations in different lineages.

The proton transport capacity of snake channel D may therefore have substantially decreased in the ancestral lineage leading to all snakes, but regained some capacity in all descendant lineages due to multiple reversion, convergent or distinctive replacements, and apparent structural functional convergent changes (Figure 3A).

Some convergent changes might be counted as parallel changes. 5.

This conclusion must be evaluated carefully because tubulins are uniquely susceptible to convergent changes.

P = Observed probability of parallel or convergent change * = Observed probability of parallel and convergent change Internodal branches are omitted.

Interestingly, the nd5, cob gene order is also found in birds [ 39], probably through a convergent change.

At the site 123 there is a convergent change of A (Ala) or Y (Tyr) to V (Val) in pig and frog PGRP-S, respectively located in the hydrophobic core.

However, Le Thierry d'Ennequin et al. (1999) noted that QTLs associated with convergent domestication in cereals actually account for < 50%% of the phenotypic variance, so selection at different loci in these crops may have been at least as influential as convergent change in achieving the domesticated phenotype.

As with convergent protein changes in multiple lineages, these parallel changes suggest similar selective pressures acting in very different species; that these changes are restricted to the posttranscriptional regulatory domains of MEIS proteins suggests that evolution may have "used" and reused a finite set of accessible mechanisms for modulation of Meis function.
